PUZZLE.

Specification of Letters Patent.

Application filed January 8, 1913.

Patented June 23, 1914. Serial No. 740,843.

To all whom it may concern:

Be it known that I, WVILLIAM EDWARD I'IEARD, resident of 142 Strachan avenue, in the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, a British subject and shipper, have invented certain new and useful Improvements in Puzzles of which the following is a specification.

The invention relates to a new form of puzzle and the object of the invention is to afford amusement and intelligent occupation for the young and the old and at the same time provide a puzzle of simple parts cheap to manufacture and therefore within easy reach of the consumer and it consists essentially of a plurality of pieces of wood or other suitable material in countersunk arrangement in relation to one another in rows and adapted to form a regular cube, the surfaces of which are each subdivided into a plurality of regular squares, the various parts being described in detail hereinafter and shown in the accompanying drawings that form part of the specification.

In the drawings Figure 1 is a perspective view of the cube complete showing the surfaces as they appear. Fig. 2 is a perspective view of number 1 layer showing the four upwardly extending tie pins. Fig. 3 is a plan view of number 2 layer on one side. Fig. 4 is a plan View of number 2 layer on the other side. Fig. 5 is a plan View of number 3 layer on one side. Fig. 6 is a plan view of number 3 layer on the other side. Fig. 7 is a plan view of number 4 layer on one side. Fig. 8 is a plan view of number 4 layer on the other side. Fig. 9 is a plan view of number 5 layer on one side. Fig. 10 is a plan view of number 5 layer on the other side, as it appears when set together and not connected with the tie pins. Figs. 11 to 14 inclusive are details of each of the tie pins, there being two views of each taken at right angles to each other. Figs. 15 to 21 inclusive are details of the blocks composing layer 1 as shown in Fig. 2. Figs. 22 to 29 inclusive are details of the blocks composing layer number 2 as shown in Figs. 3 and 4. Figs. 30 to 38 inclusive are details of the blocks composing layer 3 as shown in Figs. 5 and 6. Figs. 39 to 45 inclusive are details of the blocks composing layer 4 as shown in Figs. 7 and 8. Figs. 46 to 52 inclusive are details of the blocks composing layer 5 as shown in Figs 9 and 10.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings and first to Fig. 2, the pieces 1 have slots in which to countersink the pieces 2 and these pieces are locked by the center bar 3, while the tie pins 4 have the heads 5 at each end of the correct sizes for the squares appearing on the outer surface of the cube. These pins extend through holes in the pieces 1.

In the Figs. 3 and 4 number 2 layer is illustrated, in which the pieces 6 are crossed by the pieces 7 each one of said sets of pieces being slotted to countersink in another, so that the edges of said layer appear in the regular squares for the outer surface of the cube. The tie pin holes 8 are made through this layer in both pieces 6 and 7.

In layer 8 illustrated in Figs. 5 and 6 the formation is somewhat different and comprises corner pieces 9 extending across two sides of the layer and fitting into the corre-.

spondingly notched corner pieces 10, this layer having a through center cross piece 11 and a split piece 12, the sides of said layer showing regular squares for the outer surface of the cube. The pieces have suitable slots for countersinking.

In layer 4 the arrangement is again an arrangement of cross pieces 13 and 14 with slots for countersinking the various parts and tie pin holes left therethroug'h, the outside being in the form of the regular squares as in the other layers.

In layer 5 the arrangement of the pieces 15 and 16 is somewhat similar to the pieces in layer 1, though to vary the construction there are small pieces 17 and in consequence shorter pieces 18 in the inside construction, the general arrangement though in countersinking, leaving holes 19 for the tie pins and slots 20 at the outside for the heads of the tie pins, is the same as throughout the whole invention.

The description of the fitting of the parts together after they have been mixed up is of course left for the person who is endeavoring to solve the puzzle. The main feature of the invention is the arrangement of tie pins, locking pieces and cross pieces all with slots for countersinking, so as to present regular surfaces on the outside surface of a regular cube.

What I claim is 1. A puzzle comprising a plurality of pieces arranged to be built up in layers to form a regular cube and joined together by tie pins, the outer surfaces of said cube showing a plurality of regular squares.

2. A puzzle comprising a plurality of pieces adapted to be fitted together in layers having slots therein for countersinking the pieces one in the other, said pieces terminating at the edges of each layer in the shape of regular squares and said layers having a plurality of holes therethrough and prepared slots in the outside layers and tie pins iaving heads at each end thereof and eX- tending through said holes, said heads filling the slots in the outside layer and completing the squares in the outside surfaces of the cube.

3. A puzzle comprising a plurality of pieces crossed and countersunk one in the other, tie pins set in said pieces having heads at each end thereof, the heads being formed in the shape of squares and with all of said pieces completing a plurality of regular squares showing on all the outer sides of said layer, a second layer built up on the aforesaid layer formed of a plurality of pieces crossed by other pieces having slots for countersinking, one in the other, and holes through which said tie pins extend, the edges of said layers showing as a number of regular squares, a third layer formed of double corner pieces, the inner corner pieces having a slot to receive square corner pieces forming tie bars at their respective sides and center pieces crossed, one of said center pieces being split, the outside edge layer formed of pieces and cross pieces having holes for countcrsniking purposes and corner locking pieces correspondingly formed, said layer having holes for said tic pins and prepared slots for the heads of said tie pins, all the outer faces of said layer showing in the form of regular squares and completing the appearance of the cube as one made up ofa plurality of small cubes.

Signed at city of Toronto, Ont. this seventeenth day of December 1912.
